Guildford / Weybridge area of Surrey (and generally Surrey itself) is stupidly expensive for anything.
That seems like a decent place for £700 to be honest, I've seen some right dogs of places at £600 in the area, which are as someone earlier said, a room with a shower stuck in it, some kitchen units and a bed.
Personally though, at that sort of money I'd look to find someone to share with and spend more along the lines of £1k or so on a 2bed flat...so £500 each. I don't like living with people, but until you've got the money to live alone, sharing is often the easiest/best way to move out from parents.
I get that, but I would much sooner flatshare with someone, share living space with one other person and have my own bedroom. I am a miserable git but I would prefer that to sleeping in the living room.
